Stored data is read from a memory location at the memory address. Based on determining that the memory location was not previously modified, the stored data is compared to the write data. Based on the stored data matching the write data, the write request is completed without writing the write data to the memory and a corresponding silent store bit, in a silent store bitmap is set. Based on the stored data not matching the write data, the write data is written to the memory location, the silent store bit is reset and a corresponding modified bit is set. At least one of an application and an operating system is provided access to the silent store bitmap. | 12-29-2016 |
20160378400 | MEMORY HEALTH MONITORING - A data storage device may be configured to write first data to a first set of storage elements of a non-volatile memory and to write second data to a second set of storage elements of the non-volatile memory. The first data may be processed by a data shaping operation, and the second data may not be processed by the data shaping operation. The data storage device may be further configured to read a representation of the second data from the second set of storage cells and to determine a block health metric of a portion of the non-volatile memory based on the representation of the second data. The portion may include the first set of storage elements and the second set of storage elements. As an illustrative, non-limiting example, the first portion may be a first block of the non-volatile memory. | 12-29-2016 |
